6:5

#1
What would be the optimal bet spread to beat this game? I know, thats its probably not possible, or you do need a large bankroll, but if you are allowed (which I am), any bet spread, what is necessary?

Would a 1:12 spread be enough?

Thanks

as much as possible

If you are allowed to spread as much as you want why stop at 1:12? Why not 1:40? Or even 1:60? The more you spread the more money you can make.
